I have a CSV-file that is 4Gb large. It contains three columns Latitude, Longitude and a value. I try to use the Wizard to convert from WGS84 to a projected XY value in SWEREF TM. In Windows TaskManager I can see that when CoordTrans have assigned close to 2 Gb of memory it stops with error message: "[-2147417848] frmWizardFileConvert.bNext_Click: Automation error". Can CoordTrans handle files as large as this or not? I run v2.30 Build (185) on Windows 7 64-bit Professional.
